Images and anatomical references

In this module on the anatomy of the wrist in 3T MRI, we have captioned over 340 anatomical structures in 208 MR images of the wrist and 3D reconstructions of the carpal bones.

Anatomy of the wrist (MR) : Carpal tunnel - Ulnar canal

This module is an aid to learning and daily practice of magnetic resonance imaging of the wrist, aimed rather at a specialised audience (radiologists, surgeons, rheumatologists and physicians specialising in musculoskeletal imaging).

Images of the wrist in 3T MRI and in 3D

The MRI images of the elbow were derived from a healthy volunteer. Image acquisition was performed on a 3 Tesla MRI with a thickness of 4 mm in contiguous sections. We used the commonly used weightings (and RFP-FatSat T1) and impacts (axial, coronal and sagittal) in medical imaging studies of the wrist.

Wrist joint - MRI

The 3D images of the wrist joint and carpal bones are three-dimensional reconstructions obtained from a scanner.

Carpal bones

Captions for the anatomical structures of the carpus

340 anatomical structures of the wrist have been captioned, accessible via the "anatomical structures" tab:

General anatomy: shows the different regions of the wrist and hand (carpal, metacarpal, hypothenar and thenar eminence,)

Bone: presents the anatomy of the bones of the wrist, subdivided into radius, ulna, carpal bones (scaphoid, lunate, pisiform, triquetrum, hamatum, capitatum, trapezoid and trapezium) and the metacarpal bones

Articulation: details the different joints of the carpus, including the distal radioulnar joint, the radiocarpal, midcarpal and carpometacarpal articulations.

Ligaments: all the ligaments of the wrist visible in MRI are shown on this anatomical module, including collateral ligaments, the radiocarpal and ulnocarpal ligaments as well as the intercarpal ligaments.

Muscles: mainly the muscles of the forearm and the palmar region (muscles of the little finger, thumb muscles)

Tendons: the many tendons of the wrist are all captioned on this picture, from the tendon of the flexor carpi radials to the flexor digitorum profundus tendon.

Carpal tendon sheaths: describes the various synovial sheaths surrounding the tendons of the wrist tendon: sheath of the extensor muscles of the fingers, sheath of the flexor carpi radialis, tendon sheath of the long thumb flexor...
